  • Add support for clflush
  • Implement execve: save the existing info in shared memory and load it back
  • Fix staging files naming
  • Fix corner case scenario for dup2 where relink fails
  • Handle invalid pointer in open, rename, truncate
  • Bug in path resolution where required '/' was not included.
  • Bug in path resolution where null character was not appended after readlink
  • Bug in path resolution where the string buffer was not large enough -- changed from 256 to 4096
  • Fix bug in fallocate for staging files (number of arguments)
  • Fix bug in dup2 where the new fd vinode was being unref'd after the dup2 process, this causes new file to be closed in kernel. Moved this to caller. Also this is not required for dup and fcntl dup
